## Long description

ProXtend DCDONGLE-5525-4017-L is a compact DC power adapter dongle that converts a 5.5 mm outer / 2.1 mm inner barrel plug to a 4.0 mm barrel plug. The adapter enables straightforward compatibility between power supplies and devices with different barrel connector sizes, allowing continued use of existing adapters without modification. Designed for quick connection, it suits a range of consumer and professional electronics that use coaxial DC power connectors.
Advantages
The adapter provides a simple mechanical conversion with no tools required, maintaining reliable electrical contact and minimizing loss while preserving polarity. Its small form factor makes it portable and easy to store with power cables. The product is non-invasive — it adapts existing plugs rather than requiring rewiring or replacement of adapters — and is suitable for temporary or permanent use where connector size mismatch occurs.
Suitable for
 Laptops and netbooks with compatible barrel power input
 Routers, modems and network equipment
 CCTV cameras and DVR systems
 Portable audio equipment and small appliances that use DC barrel connectors
 Testing benches and service environments where various plug sizes are used
Key specifications
 Input barrel size: 5.5 mm outer / 2.1 mm inner
 Output barrel size: 4.0 mm outer
 Connection type: coaxial DC barrel adapter
 Material: metal contacts with insulating body
 Polarity: preserves center-positive or center-negative according to original plug orientation

How to use
Insert the source plug (5.5 mm outer / 2.1 mm inner) into the adapter’s input side until it seats firmly. Connect the adapter’s 4.0 mm output directly to the device’s barrel input. Verify the connection is snug and check device power operation. Confirm correct polarity and voltage compatibility between the power supply and the device before use to prevent damage. The adapter requires no assembly and can be attached or removed as needed.
Usage recommendations
Use the dongle only with power supplies that match the device’s required voltage and current ratings. Avoid forcing mismatched plugs; ensure a clean, debris-free connection for reliable contact. For prolonged installations, confirm the adapter does not introduce excessive strain on cables or connectors and periodically check connections for heat or wear.
